I will read the development status of cloud storage technology.

Storage has experienced product forms such as tape storage, DVR, NVR, and SAN direct storage in the development of the security industry. Emerging software definitions, cloud storage and other concepts are also emerging, but no matter how it develops, the role of storage is always written. And read two functions. Traditional distributed storage, such as DVR and NVR products, can only distribute distributed monitoring by dividing a number of monitoring areas to ensure basic write requirements, and the performance of large-scale reading cannot be met as needed. Centralized storage in the monitoring field mainly refers to SAN and all-in-one devices. These devices have achieved large-scale write space of a single machine through RAID and adding expansion cabinets, meeting the demand for high density, but still cannot read video. Do it on demand. The cloud storage architecture truly enables video write, read, on-demand distribution, and linear expansion. Adding independent storage nodes can achieve higher read and write performance.

At present, large-scale high-definition video surveillance system applications in the security industry need to meet massive HD video data storage, high-definition video data such as 720P, 1080P, 5MP, 8MP and other high-resolution IPC access, and large-channel concurrent large-stream real-time streaming. Data read and write, the performance of traditional storage faces great challenges.

High-definition display of security surveillance video images, massive unstructured data storage, multi-information fusion, analysis and mining of audio and video images, intelligent analysis and decision-making of large-scale data need to introduce various advanced technologies such as cloud computing and cloud storage, especially in In the safe city, intelligent transportation, smart city and large-scale industrial applications across the region, the demand for unstructured data storage systems such as massive video images in these industries means the improvement of data storage capacity and computing processing performance, storage products. It requires high performance, high capacity, high reliability and scalability, and needs to be deeply integrated with security industry applications to meet the special business applications of massive video data management in security systems.

At present, cloud storage has been deployed and used on a large scale in all major industry security markets. For example, the construction of smart cities and safe cities requires a massive storage system for video surveillance, and can make full use of the stored data for in-depth analysis and processing. Since traditional storage technologies cannot meet the needs of social development, the application of cloud storage in the security field will become an inevitable choice.
